Perpendicular and Parallel
Before we begin the activity, take two minutes to remind yourself the definition of "perpendicular" and "parallel" lines.
Translation (any BLUE points can be moved)
Question 1
As you experiment with translation, record your initial observations. CHALLENGE: use "parallel", "perpendicular", and/or "distance" in your answers.
Reflection (any BLUE points can be moved)
Question 2
As you experiment with reflection, record your initial observations. CHALLENGE: use "parallel", "perpendicular", and/or "distance" in your answers.
Rotation (any BLUE points can be moved)
Question 3
As you experiment with rotation, record your initial observations. CHALLENGE: use "parallel", "perpendicular", and/or "distance" in your answers.
Question 4
Why do mathematicians call these transformations "rigid"? (You may look up the definition of rigid if you do not know its meaning.)
